  comparison: less than or equal Compares whether one JSON value lhs is less than or equal to another JSON value by calculating `not (rhs < lhs)`. Parameters
  [in] | lhs | first JSON value to consider
  [in] | rhs | second JSON value to consider
  Returns whether lhs is less than or equal to rhs Complexity Linear. Exception safety No-throw guarantee: this function never throws exceptions. Example The example demonstrates comparing several JSON types. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 // create several JSON values 9 json array_1 = {1, 2, 3}; 10 json array_2 = {1, 2, 4}; 11 json object_1 = {{"A", "a"}, {"B", "b"}}; 12 json object_2 = {{"B", "b"}, {"A", "a"}}; 13 json number_1 = 17; 14 json number_2 = 17.0000000000001L; 15 json string_1 = "foo"; 16 json string_2 = "bar"; 17 18 // output values and comparisons 19 std::cout << std::boolalpha; 20 std::cout << array_1 << " > " << array_2 << " " << (array_1 > array_2) << '\n'; 21 std::cout << object_1 << " > " << object_2 << " " << (object_1 > object_2) << '\n'; 22 std::cout << number_1 << " > " << number_2 << " " << (number_1 > number_2) << '\n'; 23 std::cout << string_1 << " > " << string_2 << " " << (string_1 > string_2) << '\n'; 24 } Output (play with this example online):
      [1,2,3] > [1,2,4] false
      {"A":"a","B":"b"} > {"A":"a","B":"b"} false
      17 > 17.0000000000001 false
      "foo" > "bar" true
  The example code above can be translated with
      g++ -std=c++11 -Isingle_include doc/examples/operator__greater.cpp -o operator__greater
